LIQUID-METER... f

T0V all whom t may concern/.-

gineer, of Imbrode'rstra'sse l() and 12,Ludwigs l burg, Germany, have invented certain new. anduseful Improvements in Liquid-Meters, the Pistons of WhichConsist of Annular Diaphragms, of which the following is a clear vand perfect description.

' `This invention relates to a meter formeasuring the volume of liquids and iuids in which va ldiaphragm is actuated by `the liquid to be measured, the movements of this diaphragm being transmitted, by means of -a piston-rod in the 4usual manner to the shaft, by which the counting apparatus is actuated.

f Liquid-meters in which the diaphragm acts as the lpiston have heretofore usually been provided with two diaphragms, the action of lwhich is similar to that of the two pistons of a double-,acting pump. In the present invention ythese diaphragme, which hitherto have always been of circular shape, are formed by annular plates, the outer and* inner edges of which'are attached tothe sides of correspondingly-shaped annular casings. By adopting this form of constructing the apparatus a hollow space is created in the center of -the casings containing the diaphragm, which is best employed forv harboring the distributing mechanism.` Moreover, the supply and discharge of the liquid to ber measured takes place in the axial direction and the frictional resistance offered to the liquid'is at the same' time very 'considerably ldiminished and the whole mechanism is very much simplified, with the result that the 'liquid-meter can be litted without any diiiculties whatever. The piston-diaphragms themselves maybe in' the rvform oi' circular or elliptic rings or of rings having any desired shape. The hollow spaces in the interior of these rings may be arranged either ,concentrically or eccentrically. Conand is twisted through a right angle, so that y the inlets and outlets for the liquid of one half of the distributing mechanism in relation Speccation oil Iietters Patent.; Application ined May 25,119e5. serial No. 262,259.

As it is not possible to make the diaphragms so accurate as to insure that the amount of liquid flowing through the cylinder or the apparatus at each revolutionv of the shaft shall f always be the same and represent apreviously-determined quantity and as, moreover,

even a small inaccuracy in the action of the diaphragms must result in making the amount of the liquid actually passing through the apparatus much larger than'the' amount indiv cated by the counting mechanism, especially whenthe apparatus has been in use for a considerable time, the apparatus has been provided with a device for regulating the amount of the liquid coming through by means ot' which the stroke ofv the piston-diaphragm can be so adjusted as to allow only a iixed quantity of liquid to pass through the apparatus at eachL revolution of the main shaft. 'l

1n the annexed drawings two different forms of constructing the apparatus are illustrated by way of example.

6 is a vertical section through a modication of the liquid-meterillustrated in the preceding drawings,inwhich the'distributing mechanism is arranged eccentricallyinthe interior of the piston-diaphragm. 7 is an end view of t the meter.A

In the -annular casings 1,v each of which is divided -into two halves, diaphragms 5, covered with metal plates 6, are'so attached tok the casings 1 by their inner and outer circumferences as to be capable of oscillating to and fro.v The cylindrical casings l are pro- .vided on the inside with annular flanges 3 and are connected with the casings 2 .by means of screwsft. The diaphragms 5 are maintained in position by means of the screws 7,. by which the two halves of the cylindrical casing are,

fastened to eachother. In eachl annularcylinder 1 two apertures leading into the inner hollow spaces 9, are arranged insucha manner that' one'ofv ,them is situated onv the one IOO side and the other on the other side of the diaphragm.

The distributing mechanism 10 for the liquid is arranged within the hollow space 9. It consists in the case of the apparatus under consideration of a tubular rotary valve 11, provided with eight apertures 12, corresponding to the apertures 8. All the apertures which correspond to those of one of the diaphragm-cylinders are situated on the same side of the tubular rotary valve, while those that correspond to the apertures of the other cylinder are situated at an angle of ninety degrecs in relation to the others. A partition 13, which divides the tubular rotary valve 11 into two parts, is twisted through ninety degrees and is bent at right angles, so as to form two walls 14, which each cover one-half of the inlet and outlet ends of the tubular rotary valve and which in consequence of the twisting of the partition are displaced through an angle of ninety degrees in relation to each other. The arrangement advocated insures that the piston-diaphragms are so operated that each of them is at its most eective position when the other is at its dead-point. Moreover, by arranging the diaphragms in the manner of the pistons of a double-acting pump at least a section of them must always be in full action. The diaphragms are not, as has heretofore always been the case, connected with the shaft actuating` the counting mechanism by means of piston-rods or connecting-rods, but by means of a crank-shaft 15, which actuates the crank 18 of the main shaft 17. The crankshaft 15 is attached to the diaphragms 5 by hinges 16 and moves in a recess 19 of the cylindrical casing. The liquid is prevented from running out of the casing by a diaphragm 20, which covers the recess 19 and one end of which is attached to the casing 1 by a ring 2l and screws 22, while the other end of it is fixed between the hinge 16 and the diaphragm 5. Asis shown in Fig. 2, the diaphragm 20 must oscillate in a manner that corresponds to the movements of the crankshaft 15 and the piston-diaphragms 5.

The distributing mechanism 10 is driven from the main shaft by means of a pair of helical tooth-wheels of equal diameter. For this purpose the tooth-wheel 23, which engages with the tooth-wheel 24, mounted on the tubular yrotary valve 10, is mounted on the main shaft 17. Moreover, a bevel-wheel 30, which is in engagement with -the bevelwheel 26, actuating the shaft 27 of the counting mechanism, is likewise mounted on lthe main shaft 17 To insure the proper movements of the diaphragms 5 when oscillating, pins 28, which move in cylindrical projections 29, attached to the casings 1, are fixed to the piston-diaphragms 5 in the usual manner.

Fig. 6 shows a different form of constructing the distributing mechanism. In this instance the pistons are formed of eccentric rings and not of concentric rings, as in the apparatus already described. A hinged piece 34, with which the main shaft 15 engages, is fixed to the piston-diaghragm 5. The cylindrical part of the hinged piece 34 enables the small diaphragm 20 to oscillate to the same extent in both directions. A mud-catch 31, which is closed by the screw 33 and in which a removable sieve 32 is arranged, is fixed to the. inlet-pipe of the casing l. The sieve 32 serves to prevent solid and like particles from entering the apparatus, and thereby avoid (le-- stroying the working or operation of the latter. After unscrewing the cover 33 the sieve 32 may be taken out for cleaning or repairing purposes. The particles that have a tendency to enter the apparatus collect in a space adjacent to the lower extremity of the sieve.

Finally, regulating devicesfor instance, screws 35, by means of which the height of the stroke of the diaphragm can be regulated as required-are attached to the guides 29 of the guide-pistons 28 of the diaphragms 5.'

The apparatus is operated as follows: When the different parts of the apparatus are all in the position shown in Fig. 1, the liquid, which flows through the meter in the direction indicated by the arrows, enters the distributing mechanism from the right. passes through the lower aperture 8 into the right cylinder and forces the diaphragm to the right, whereupon the whole quantity of liquid in this cylinder enters the distributing mechanism through the upper aperture 8 and iiows from thence into the left cylinder. While the parts of the apparatus are in this position the apertures 3 of the left cylinder remain closed. 'Ihe pressure of the entering water actuates not only the right piston-diaphragm but also the main shaft 17, the rotation of which will rotate the distributing mechanism through a right angle and cause it to assume the position shown in Fig. 5, in which both the apertures of the right diaphragm-cylinder are closed while there is a free passage from the apertures of the left diaphragm-cylinder to the distributing mechanism. Consequently the liquid which fills the left half of the left cylinder must force the liquid which lills the right half of the left cylinder to liow into the distributing mechanism. If the latter is again rotated through a right angle, the liquid will pass through the upper aperture of the right cylinder into the right half of this cylinder and will force the water to run out of the left half of the cylinder, &c.

Having now particularly described and ascertaned the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a liquid-lneter, annular casings and pistons consisting of annular diaphragms disposed in the interior of the casings and attached to the latter.
